6. Advanced Features

6.1 TH2MQTT Home Assistant Integration

The eTHS sensor supports TH2MQTT, a bridge that connects the temperature and humidity sensor to Home Assistant using the MQTT protocol. This enables advanced automation scenarios.

• Monitor and react to changes in temperature and humidity within Home Assistant.
• Trigger actions such as turning on an air conditioner when the temperature is too high or activating a humidifier when humidity drops below a certain level.
• Automate your home environment based on real-time data.

6.2 Using Temperature/Humidity as Alexa Routine Triggers

While Alexa natively supports motion sensors as routine triggers, temperature and humidity sensors are not directly supported as events. However, LinknLink provides a smart workaround using a virtual "Toggle" device.

Video 1: Tutorial on how to use the LinknLink eTHS sensor to trigger Alexa Routines based on temperature or humidity changes. This video demonstrates the process of creating a virtual toggle device in the LinknLink app and linking it to Alexa to enable advanced automation.

1. Create a Virtual Toggle Device: In the LinknLink app, navigate to "Smart Services" and create a "Toggle State" device. This virtual device has two states: "Triggered" and "Standby".
2. Link to Alexa: The "Toggle" device will be discovered by Alexa as a motion sensor, which also has two states: "Motion Detected" and "No Motion Detected". These states will mirror the "Triggered" and "Standby" states of your virtual toggle.
3. Create Routines in LinknLink App:
   • Create a routine where the eTHS temperature rising above a certain threshold (e.g., 25°C) changes the "Toggle" device state to "Triggered".
   • Create another routine where the eTHS temperature dropping below a certain threshold (e.g., 24°C) changes the "Toggle" device state to "Standby".
4. Create Routines in Alexa App:
   • Create an Alexa routine where "When Toggle detects motion" (i.e., temperature is high), Alexa performs a desired action (e.g., turns on a smart fan, sends a notification).
   • Create another Alexa routine where "When Toggle detects no motion" (i.e., temperature is normal/low), Alexa performs another action (e.g., turns off the smart fan, sends a notification).

This method effectively uses the virtual toggle as an intermediary to allow temperature and humidity changes to trigger Alexa routines, expanding your home automation possibilities.
